(you will have to play around with the lat and long to make sure they cover the area you want e.g. in the above example I made it so that bounderies were: clark park to the south and east, connaught park to the west and stanley park to the north)

If you know how to run MongoDB and ruby on your computer or your server, then backupPublicPhotoMetadataByDateAndUser.rb is a simple Ruby script to backup your Flickr metadata for yours (or anybody else's) Flickr public photos for a given time period. Simple (it doesn't replicate flickr's richness nearly as comprehensively as Aaron's parallel flickr) but effective because then you can with very very simple programming use the MongoDB query language to do useful Flickr queries such as:

1. give me all the photos in gastown

2. give me the square 75x75url of all photos in Vancouver tagged "yellow"

3. give me all the photos geo-tagged in the city of Vancouver taken in 2011 during the morning rush hour (e.g. if you wanted to do Eric Fisher-like maps)

HOW TO RUN IT:

Start up MongoDB and create some indexes: /Applications/mongodb-osx-x86_64-2.0.2/bin/mongo
